NEET BIOLOGY

Detailed explanation-1: -Glucose is used by cells so as to form Energy(ATP). They are necessary for cellular respiration in the mitochondria. Hence the correct option is option B i.e. carbohydrates. Additional information:-Lipids: They are the second source of energy after carbohydrates.

Detailed explanation-2: -Most of the energy required by the human body is provided by carbohydrates and lipids; in fact, 30-70% of the energy used during rest comes from fat. As discussed previously, glucose is stored in the body as glycogen. While glycogen provides a ready source of energy, lipids primarily function as an energy reserve.

Detailed explanation-3: -Food Sources of Lipids Dietary lipids are primarily oils (liquid) and fats (solid). Commonly consumed oils are canola, corn, olive, peanut, safflower, soy, and sunflower oil. Foods rich in oils include salad dressing, olives, avocados, peanut butter, nuts, seeds, and some fish.

Detailed explanation-4: -Excess carbohydrates are stored as fat. Provide the most energy-rich chemical bonds, but are more difficult to break down. They are considered a secondary source of energy. Fats are easily stored in the body.
